The following displays pertain to the Heat cycle:
While in the Heating phase, you will see this display. It
shows the present temperature of the hopper.
MODE: HEAT
PHASE: HEAT
HOPPER TEMP: 140.0 F
BRUSH CLEAN ON: MM/DD
The mix temperature must be raised above 151°F
(66.1°C) within 90 minutes or the freezer will be locked in
Standby, and the cycle failure display will appear.
In the example, the hopper temperature is 140°F (60°C).
The phase shows that the machine is in the Heat phase
of the Heat Treatment cycle.
When the Heat phase is complete, the freezer goes into
the Hold phase of the cycle. The Hold phase will hold the
temperature above 151°F (66.1°C) for a minimum of 30
minutes.

In this example, the hopper temperature is 151°F
(66.1°C).
MODE: HEAT
PHASE: HOLD
HOPPER TEMP: 151.0 F
BRUSH CLEAN ON: MM/DD
The final phase of the Heat Treatment cycle is the Cool
phase. Now the freezer must cool the mix below 41°F
(5°C). If the product fails to cool in 2 hours, the freezer
will lock out.
This example illustrates that the temperature is being
lowered but has not yet reached the set point.
MODE: HEAT
PHASE: COOL
HOPPER TEMP: 55.0 F
BRUSH CLEAN ON: MM/DD
The entire Heat Treatment cycle must be completed in 4
hours.
5-4
When the entire Heat cycle has been completed, the
normal display will show the machine in the Standby
mode. The machine may now be placed in the Auto
mode or left in the Standby mode.
MODE: STANDBY
HOPPER TEMP: 41.0 F
BRUSH CLEAN ON: MM/DD
Hard Lock: There are two causes for a hard lock:
1. Fourteen days have elapsed since the last 
brush-cleaning. The following screen will be
displayed:
2. There has been a thermistor failure (freezing
cylinder, hopper, or glycol) during the Heat Treatment
process.
All four LEDs on the front of the freezer will light. Press
the SEL key.
The next display is the screen that appears after the
failure message. To comply with health codes, Heat
Treatment system freezers must complete a Heat
Treatment cycle daily and must also be brush-cleaned
every 14-days. Brush-cleaning includes the normal
disassembly and cleaning procedures. Failure to follow
these guidelines will cause the control to lock the freezer
out of the Auto mode. Press the WASH key.
